Ah, pcall() is passed a _function_, so you need to do this:
local ok, s = pcall(function() return filters:add(123) end)
Here ok will be true or false depending on whether the code threw an
error; s will then be the error, or the result of the function if
successful.
In your case, could also do
local ok, s = pcall(filters.add,filters,123)
since pcall() can take arguments.
